Re: TI-H: I'm baaaaaacccccckkkk!!!
A bit of IBM TR trivia for a little offtopic hilarity...
IBM Token Ring connects inside the MAU (analogous to an ethernet hub)
to a ring. On the MAU, there are RI and RO (Ring In and Ring Out respec)
so that the internal ring of one MAU can be unionized with the internal
ring of another MAU. This is very similar to the point that
10baseT (and higher) ethernet hubs actually contain a linear (two-ended,
terminated on each end) bus with an arbitrary number of connections coming
from that, some or all of which may link to either a MAU (this is MAU as
in the ethernet definition, not anywhere near the same as a TR MAU --
ethernet MAU = MAC (Media Access Contrlr -- NOT Macintosh)) or another
terminated bus. Sound familiar? It should: 10baseT is 10base2/5 in a
box with nice tidy twister pair hanging out.
So, TR MAUs are rings in a box, and ether hubs are busses in a box.
Simple... Also, most TR MAUs have twisted-pair connectors and bear a
striking resemblence to your average ethernet hub... Of course, there's
MAUs with hermaphroditic connectors that look absolutly nothing like hubs
at all...but they do bite, which makes them quite enjoyable to work
with... It's nice when everything is genderless...
Back to the normal spilage of content-less offtopic dribble...
